Groundbreaking find makes compelling case that humans were lighting fires much earlier than originally believed Humans mastered the art of creating fire 400,000 years ago, almost 350,000 years earlier than previously known, according to a groundbreaking discovery in a field in Suffolk. It is known that humans used natural fire more than 1m years ago, but until now the earliest unambiguous example of humans lighting fires came from a site in northern France dating from 50,000 years ago.

To find out where the science stands, and how worried we should be about the potential of AI to change how we think, Ian Sample hears from Madeleine Finlay and Sam Gilbert, professor of neuroscience at University College London
